Bought the 2005 Z-4 BMW used from a dealer in high point nc. Drove it and enjoy driving until the warm weather. The steering sticks to a point of being dangerous. To compensate, I steer to the left and car pulls to the left then I bring the steering back towards the center and feel it sticking so I compensate by steering to the right. The whole time down the highway I fear for my life driving this car. I really had to concentrate to keep the car from steering off the road and I'm sure it appears I'm driving erratically to others on the road. The warm weather will soon be here in North Carolina and I'm just scared to drive it. The car otherwise is beautiful. But if I'm going to be a repeat customer to the BMW line I need to get this fixed or they should recall it and I don't feel that I should have to pay for this problem and sounds like many many others have had the exact same problem from what my research shows me. Please help before someone is killed. Seriously I'm scared ! I contacted BMW in Ohio and they need me to validate the problem through a dealer which I will do but I have to wait til the weather is warm again. Luckily I am employed and will be able to pay the $125 diagnostic fee. The consumer also stated every time she rode over a bump in the road, the radio would shut off and then come back on at random times. The dealer was unable to find any loose wires. Also, the oil filter housing was leaking and an oil leak separator was sauing air to dispel into the engine. Updated IVOQ 04/16/13
